High-Linearity, 815MHz to 1000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
Features
The MAX2031 high-linearity passive upconverter or
downconverter mixer is designed to provide +36dBm
IIP3, 7dB NF, and 7dB conversion loss for an 815MHz
to 1000MHz RF frequency range to support GSM/cellular base-station transmitter or receiver applications.
With a 960MHz to 1180MHz LO frequency range, this
particular mixer is ideal for high-side LO injection architectures. For a pin-to-pin-compatible mixer meant for
low-side LO injection, contact the factory.

♦ Integrated RF and LO Baluns
♦ Low -3dBm to +3dBm LO Drive
♦ Built-In SPDT LO Switch with 49dB LO1 to LO2
Isolation and 50ns Switching Time
♦ Pin Compatible with the MAX2039/MAX2041
1700MHz to 2200MHz Mixers
♦ External Current-Setting Resistor Provides Option
for Operating Mixer in Reduced-Power/ReducedPerformance Mode
♦ Lead-Free Package Available
In addition to offering excellent linearity and noise performance, the MAX2031 also yields a high level of component integration. This device includes a doublebalanced passive mixer core, a dual-input LO selectable switch, and an LO buffer. On-chip baluns are also
integrated to allow for a single-ended RF input for
downconversion (or RF output for upconversion), and
single-ended LO inputs. The MAX2031 requires a nominal LO drive of 0dBm, and supply current is guaranteed
to be below 100mA.
The MAX2031 is pin compatible with the MAX2039/
MAX2041* 1700MHz to 2200MHz mixers, making this
family of passive upconverters and downconverters
ideal for applications where a common PC board layout
is used for both frequency bands.
The MAX2031 is available in a compact 20-pin thin
QFN package (5mm x 5mm) with an exposed paddle.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.

All limits include external component losses. Output measurements are taken at IF or RF port of the Typical Application Circuit.
Operation outside this range is possible, but with degraded performance of some parameters.
Guaranteed by design.
Compression point characterized. It is advisable not to continuously operate the mixer RF/IF inputs above +12dBm.
Measured with external LO source noise filtered, so its noise floor is -174dBm/Hz. This specification reflects the effects of all SNR
degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.

Detailed Description
The MAX2031 can operate either as a downconverter or
an upconverter mixer that provides approximately 7dB of
conversion loss with a typical 7dB noise figure. IIP3 is
+36dBm for both upconversion and downconversion
modes. The integrated baluns and matching circuitry
allow for 50Ω single-ended interfaces to the RF port and
the two LO ports. The RF port can be used as an input
for downconversion or an output for upconversion. A single-pole, double-throw (SPDT) switch provides 50ns
switching time between the two LO inputs with 49dB of
LO-to-LO isolation. Furthermore, the integrated LO buffer
provides a high drive level to the mixer core, reducing
the LO drive required at the MAX2031’s inputs to a
-3dBm to +3dBm range. The IF port incorporates a differential output for downconversion, which is ideal for
providing enhanced IIP2 performance. For upconversion, the IF port is a differential input.
Specifications are guaranteed over broad frequency
ranges to allow for use in cellular band WCDMA,
cdmaOne™, cdma2000, and GSM 850/GSM 900 2.5G
EDGE base stations. The MAX2031 is specified to operate over an 815MHz to 1000MHz RF frequency range, a
960MHz to 1180MHz LO frequency range, and a DC to
250MHz IF frequency range. Operation beyond these
ranges is possible; see the Typical Operating
Characteristics for additional details.
The MAX2031 is optimized for high-side LO injection
architectures. However, the device can operate in lowside LO injection applications with an extended LO
range, but performance degrades as fLO decreases. See
the Typical Operating Characteristics for measurements
taken with fLO below 960MHz. For a pin-compatible
device that has been optimized for LO frequencies below
960MHz, contact the factory.
RF Port and Balun
For using the MAX2031 as a downconverter, the RF
input is internally matched to 50Ω, requiring no external
matching components. A DC-blocking capacitor is
required because the input is internally DC shorted to
ground through the on-chip balun. For upconverter
operation, the RF port is a single-ended output similarly
matched to 50Ω.
LO Inputs, Buffer, and Balun
The MAX2031 is optimized for high-side LO injection
architectures with a 960MHz to 1180MHz LO frequency
range. For a device with a 325MHz to 850MHz LO frequency range, contact the factory. As an added feature, the MAX2031 includes an internal LO SPDT switch
that can be used for frequency-hopping applications.
The switch selects one of the two single-ended LO
ports, allowing the external oscillator to settle on a particular frequency before it is switched in. LO switching
time is typically less than 50ns, which is more than adequate for nearly all GSM applications. If frequency hopping is not employed, set the switch to either of the LO
inputs. The switch is controlled by a digital input
(LOSEL): logic-high selects LO2, logic-low selects LO1.
To avoid damage to the part, voltage MUST be applied
to VCC before digital logic is applied to LOSEL (see the
Absolute Maximum Ratings). LO1 and LO2 inputs are
internally matched to 50Ω, requiring an 82pF DC-blocking capacitor at each input.

High-Linearity, 815MHz to 1000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
High-Linearity Mixer
The core of the MAX2031 is a double-balanced, highperformance passive mixer. Exceptional linearity is provided by the large LO swing from the on-chip LO buffer.
Differential IF
The MAX2031 mixer has a DC to 250MHz IF frequency
range. Note that these differential ports are ideal for providing enhanced IIP2 performance. Single-ended IF
applications require a 1:1 balun to transform the 50Ω differential IF impedance to 50Ω single-ended. Including
the balun, the IF return loss is better than 15dB. The differential IF is used as an input port for upconverter operation. The user can use a differential IF amplifier following
the mixer, but a DC block is required on both IF pins.
Applications Information
Input and Output Matching
The RF and LO inputs are internally matched to 50Ω. No
matching components are required. As a downconverter, the return loss at the RF port is typically better than
15dB over the entire input range (815MHz to 1000MHz),
and return loss at the LO ports are typically 15dB
(960MHz to 1180MHz). RF and LO inputs require only
DC-blocking capacitors for interfacing.
An optional L-C bandpass filter (BPF) can be installed at
the RF port to improve upconverter performance. See
the Typical Application Circuit and Typical Operating
Characteristics for upconverter operation with an L-C
BPF tuned for 810MHz RF frequency. Performance can
be optimized at other frequencies by choosing different
values for L1 and C4. Removing L1 and C4 altogether
results in a broader match, but performance degrades.
Contact factory for details.
The IF output impedance is 50Ω (differential). For evaluation, an external low-loss 1:1 (impedance ratio) balun
transforms this impedance to a 50Ω single-ended output (see the Typical Application Circuit).
Bias Resistor
Bias current for the LO buffer is optimized by fine tuning resistor R1. If reduced current is required at the
expense of performance, contact the factory for details.
If the ±1% bias resistor values are not readily available,
substitute standard ±5% values.
Layout Considerations
A properly designed PC board is an essential part of
any RF/microwave circuit. Keep RF signal lines as short
as possible to reduce losses, radiation, and inductance. For the best performance, route the ground-pin
traces directly to the exposed pad under the package.
The PC board exposed pad MUST be connected to the
ground plane of the PC board. It is suggested that multiple vias be used to connect this pad to the lower-level
ground planes. This method provides a good RF/thermal conduction path for the device. Solder the exposed
pad on the bottom of the device package to the PC
board. The MAX2031 evaluation kit can be used as a
reference for board layout. Gerber files are available

Exposed Pad RF/Thermal Considerations
The exposed paddle (EP) of the MAX2031’s 20-pin thin
QFN-EP package provides a low-thermal-resistance
path to the die. It is important that the PC board on
which the MAX2031 is mounted be designed to conduct heat from the EP. In addition, provide the EP with
a low-inductance path to electrical ground. The EP
MUST be soldered to a ground plane on the PC board,
either directly or through an array of plated via holes.

MAX2031
A two-stage internal LO buffer allows a wide inputpower range for the LO drive. All guaranteed specifications are for a -3dBm to +3dBm LO signal power. The
on-chip low-loss balun, along with an LO buffer, drives
the double-balanced mixer. All interfacing and matching components from the LO inputs to the IF outputs
are integrated on-chip.
